OncoGenex Pharmaceuticals Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to the investigation of custirsen when administered in combination with cabazitaxel/prednisone for the treatment of men with metastatic castrate-resistant prostate cancer (CRPC) following prior treatment with a docetaxel-containing regimen.

 

Fast track is a process designed to facilitate the development, and expedite the review, of drugs to treat serious conditions and fill an unmet medical need.  The purpose is to get important new drugs to the patient earlier.

 

The international, randomized, open-label Phase 3 AFFINITY trial is designed to evaluate if custirsen, when combined with second-line chemotherapy cabazitaxel and prednisone, has the potential to improve survival outcomes for prostate cancer patients compared to second-line chemotherapy alone. AFFINITY will enroll approximately 630 men and is expected to complete enrollment in the second half of 2014.

 

Custirsen has also received Fast Track designation from the FDA for treatment of patients with metastatic non-small cell lung cancer as part of the Phase 3 ENSPIRIT trial and for men with metastatic CRPC as part of the Phase 3 SYNERGY trial. Enrollment in the ENSPIRIT trial is ongoing and top-line survival results from SYNERGY are expected by mid-2014.
